US Customs and Border Protection (CBP) officers are primarily checking your identity, admissibility, and intent. During the interview, they verify that your passport and visa are valid and that your biometric data (fingerprints and photo) matches their records. They will ask specific questions to confirm that your intent matches your visa type; for example, if you are on a tourist visa, they are looking for signs that you might actually be planning to work or overstay. Officers check for "ties to your home country," such as a return ticket, employment, or property. They also check for customs violations, asking about food, large amounts of currency, or prohibited items. In 2026, they may also perform a digital check, which can include a request to inspect your phone or social media if they have "reasonable suspicion." Ultimately, the officer's goal is to ensure you do not pose a security threat and that you intend to follow the legal conditions of your stay before granting you "Port of Entry" clearance.
